Briefly explain the concepts of frequency reuse in the cellular system [4 marks] (a) (ii having a radius of 0.64km and a co-channel reuse factor of 12 determine the distance for the nearest co-channel cell1 for a cell that [hint: frequency reuse ratio, q r [6 marks] (b) the first generation cellular advanced mobile phone service (amps) system is allocated 25mhz band with 21 control channels for one direction communication at 800mhz range. the total bandwidth required for communication is 50mhz. the frequency separation between the uplink and downlink is 45mhz. the guard band is 40khz and each simplex channel is 30khz determine the total numbers of channels within the system [5 marks] determine whether the amps system is simplex, half-duplex or duplex [5 marks] 11 (iii) 352 at 880.560mhz find the transmission frequency of a mobile subscriber unit transmitting on channel 352 consider the base station transmits control information on channel

The bubba chump shrimp company processes and packages shrimp for sale to wholesale seafood distributors. the shrimp are transported to the main plant by trucks that carry 1,000 pounds (lb) of shrimp. once the continuous flow processing of the shrimp begins, no inventory is allowed in buffers due to spoilage and all of the shrimp must be processed within 12 hours to prevent spoilage. the processing begins at the sorter, where the trucks dump the shrimp onto a conveyor belt that feeds into the sorter, which can sort up to 500 lb per hour. the shrimp then proceed to the desheller, which can process shrimp at the rate of 400 lb per hour. however, after 3 hours and 45 minutes of processing, the desheller must be stopped for 15 minutes to clean out empty shrimp shells that have accumulated. the veins of the shrimp are then removed in the deveining area at a maximum rate of 360 lb per hour. the shrimp proceed to the washing area, where they are processed at 750 lb per hour. finally, the shrimp are packaged and frozen. what is the daily process capacity of the processing plant (excluding the packaging and freezing)?

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?
